ABSTRACT:
A digital-to-analog converter is provided which compensates for relative errors among weighting elements used for D/A conversion. The converter includes a decoder, a rotator, and a weighting section. The rotator receives decoded signals from a decoder to produce rotated output signals for activating or deactivating a plurality of weighting elements, respectively, included in the weighting section. The rotated output signals assure that the same number of weighting elements are activated in each of a plurality of sub-periods of time constituting a main period of time of the D/A conversion and that each of the plurality of weighting elements is activated the same number of times during the whole main period.
